inconsistent handling of lists

inconsistent handling of lists

I'm seeing some inconsistent handling of lists in a commonmark document. 
Afaict a list with a single item is treated slightly differently from lists 
with multiple items.

The document (not including %%% etc):

%%%%%%
- foo
  + foo 1

- bar

blabla

- baz
  + baz 1
%%%%%%

Output:

<ul>
<li><p>foo</p>
<ul>
<li>foo 1</li>
</ul></li>
<li><p>bar</p></li>
</ul>
<p>blabla</p>
<ul>
<li>baz
<ul>
<li>baz 1</li>
</ul></li>
</ul>

I would have expected "foo" and "baz" to either both be in p tags or none 
of them. The resulting html ends up looking wonky.

Adding another list item below "baz" makes a difference:

<ul>
<li><p>foo</p>
<ul>
<li>foo 1</li>
</ul></li>
<li><p>bar</p></li>
</ul>
<p>blabla</p>
<ul>
<li><p>baz</p>
<ul>
<li>baz 1</li>
</ul></li>
<li><p>yo</p></li>
</ul>

Note that "baz" is now in p tags, same as "foo".

Pandoc installed using homebrew:

$ pandoc --version
pandoc 1.18
Compiled with pandoc-types 1.17.0.4, texmath 0.8.6.6, highlighting-kate 
0.6.3

Oh, I should probably state how I'm running pandoc:

pandoc -f commonmark -o foo.html foo.md

Re: inconsistent handling of lists

[John MacFarlane]

See the CommonMark spec for the distinction between
"tight" and "loose" lists.

You have two lists.  The first,

- foo
  + foo 1

- bar

is "loose" because of the blank space between items.

The second,

- baz
  + baz 1

is tight because there is no blank space between items.

You might say:  if you have a one-element list, how can
you put blank space between items?  Of course you can't.
So such lists are always tight.  I don't know a better
solution.
